Ice Glide (Su)

A burrowing ice elemental can pass through nonmagical ice and snow as easily as a fish
swims through water. Its burrowing leaves behind no tunnel or hole, nor
does it create any ripple or other sign of its presence. A control water
spell cast on an area containing a burrowing ice elemental flings the
elemental back 30 feet, stunning the creature for 1 round unless it
succeeds on a DC 15 Fortitude save.

Icewalking (Ex)

This ability works like the spider climb
spell, but the surfaces the elemental climbs must be icy. The elemental
can move across icy surfaces without penalty and does not need to make Acrobatics checks to run or charge on ice.

Numbing Cold (su)

When an ice elemental deals cold damage to a creature, that creature must succeed on a Fortitude save or be staggered for 1 round. The save DC is listed in the elemental’s stat block and is Constitution-based.

Snow Vision (Ex)

An ice elemental can see perfectly well in snowy conditions and does not take any penalties on Perception checks while in snow.

ECOLOGY

Environment any land or water (Plane of Water)Organization solitary, pair, or gang (3–8)Treasure none

Ice elementals
are creatures made of animated snow and ice. They form in especially
cold parts of the Plane of Water and along its border with the Plane of
Air, where giant icebergs careen off of world-high waterfalls into the
open sky. Ice elementals vary in their exact appearance.
